alzheimers gut mental healthThe role of the gut microbiome in causing Alzheimer’s disease has finally been confirmed.

Using gut microbiota transplants, an international team of researchers has shown memory impairments in humans with Alzheimer’s can be passed on to young, healthy rats.

The study also revealed specific bacteria in the gut are directly linked to cognitive decline in Alzheimer’s patients.

This highlights the gut microbiome as a key area of research for Alzheimer’s and other forms of dementia, and that could lead to new ways to treat the disease.

“People with Alzheimers are typically diagnosed at or after the onset of cognitive symptoms, which may be too late, at least for current therapeutic approaches,” says neuroscientist Yvonne Nolan from University College Cork (UCC) in Ireland.

“Understanding the role of gut microbes during prodromal – or early stage- dementia – before the potential onset of symptoms may open avenues for new therapy development, or even individualized intervention.”
